The MAX20037/MAX20038 ICs combine a 3.5A automotive-grade step-down converter, USB host chargeradapter emulator, and USB protection switches for automotiveUSB host applications. The device family alsoincludes a USB load current-sense amplifier and configurablefeedback-adjustment circuit, designed to provideautomatic USB voltage compensation for voltage dropsin captive cables often found in automotive applications.The ICs limit the USB load current using both a fixedinternal peak-current threshold of the DC-DC converterand a user-configurable external USB load current-senseamplifier threshold.The ICs allow flexible configuration options for bothstand-alone and supervised applications, and can be programmedfor desired operation using both external programmingresistors and/or internal I2C registers throughthe I2C bus.The ICs are optimized for high-frequency operation andinclude programmable frequency selection from 310kHzto 2.2MHz, allowing optimization of efficiency, noise, andboard space based on application requirements. Thefully synchronous DC-DC converters feature integratedhigh-side and low-side MOSFETs, an external SYNCinput/output, and can be configured for spread-spectrumoperation.The MAX20037/MAX20038 are available in a small (5mmx 5mm) 28-pin TQFN package (side-wettable available)designed to minimize required components and layout area.Design Solution: Add Even More USB Ports to Your Car—In Less Space ›ApplicationsAutomotive Connectivity/TelematicsAutomotive Radio and NavigationDedicated USB Charging Port (DCP)USB Port for Host and Hub Applications
